I don't think they will be dragon only because gen 4's legends were based off them. My guess is it'll be flying, maybe ghost (hoping) some new type, or no second type, and their first type will be dark/psychic, dark/ light, or something like that.
Zekrom, and Reshiram looks cool too. I wonder what the third will be.
